The SPT sampler is an in-situ testing method used in the field of geotechnical investigations to obtain a soil sample by driving a penetrator at the bottom of an auger rod into the soil at the bottom of a borehole using an SPT hammer. This test method is known as the Standard Penetration Test (SPT), where the number of hammer strokes required to penetrate 300 mm (1 ft) is called the Standard Penetration Strike (N-value), which relates to the strength of the soil. However, when different types of SPT hammers are used for testing, different hammering efficiencies affect the value of the N-value. In order to solve this problem, PDI (USA) has developed the Standard Penetration Test Analyzer, which determines the converted energy of the hammer blow by measuring the force and velocity values during the hammer blow in the test. This analyzer measures the ratio between the actual energy transferred to the drill pipe by the hammer blow and 60% of the theoretical potential energy, and then multiplies it with the measured standard penetration number (N-value) to get the corrected standard penetration number (N-value), which improves the reliability of the soil strength valuation obtained by the standard penetration test, and makes it more suitable for a variety of geotechnical engineering applications.

The Use of SPT Sampler
SPT samplers are mainly used for water quality sampling, especially automatic water quality samplers such as SPT84HC-9601 automatic water quality sampler (mixed sampling portable), able to carry out water quality monitoring and assessment. These samplers are typically used to collect water samples in order to analyze the various chemical constituents, microorganisms, and physical properties of the water in order to assess the safety and suitability of the water quality. They have a wide range of applications in environmental monitoring, water resource management, wastewater treatment, etc., helping professionals to understand water quality conditions, identify and solve water pollution problems in a timely manner, and protect water resources.
SPT samplers may also involve the sampling of other types of samples, such as phosgene test strips, gas analyzers, proton exchange membranes, fuming pens, and other products, which are widely used in the fields of industrial safety, environmental monitoring, and scientific research for detecting and evaluating a wide range of gas compositions, water quality parameters, and so on.23 For example, phosgene test strips are used for the detection of hazardous gases, such as phosgene. This is essential for safety monitoring in industrial production and laboratory research.
Analog input: First, the analog input converts the incoming continuous signal into a current or voltage signal.
Sampling: The sampler uses a clock signal to sample the input signal, i.e., the continuous signal is discretized into a series of sample values at a certain frequency.
Quantization: Finally, the sampler also needs to quantize these sample values to convert them into digital signals.
SPT Sampler Technical Standards
Flow range: Different SPT sampler models have different flow ranges. For example, the SPT/TY-500H model fully automatic atmospheric sampler has a flow range of (400-600) mL/min.1 The TSP sampler has a flow range of (50-135) L/min with a resolution of 0.1 L/min.
Continuous working time: The SPT/TY-500H model has a continuous working time of more than 8 hours.
Operating Temperature: SPT/TY-500H model's operating temperature range is (-10～55)℃.
Maintenance of SPT Sampler
Regular inspection and maintenance: Regularly check whether the parts and connecting wires are intact and undamaged, and deal with any problems found in time. If you encounter a malfunction or need to replace a part, you should contact the equipment manufacturer or a professional technician for repair to ensure proper operation and avoid further damage.
Cleaning and dustproofing: Since the sampler is usually placed in an industrial environment or outdoor place, it is easily affected by dust, oil and other pollutants. Therefore, the sampler should be cleaned and dustproofed regularly by gently wiping the surface and connection ports with a clean, soft cloth, and consider installing a dust cover or using a dust sleeve to minimize the entry of dust and contaminants.
Power management: Ensure that the sampler is connected to a stable and reliable power source to avoid frequent power outages and voltage fluctuations. When not in use for a long period of time, it is recommended to disconnect the power supply and store it in a dry and ventilated place to avoid damage caused by humidity and overheating.
Software updates and upgrades: As technology advances, software needs to be updated and upgraded on a regular basis, including fixing bugs, adding new features and improving system performance. Users should pay attention to the software update information released by the equipment manufacturer, and follow the instructions to operate, and backup important data to prevent accidental loss.
Temperature and humidity control: Proper temperature and humidity are critical to the performance and life of the sampler. Ensure that the ambient temperature and humidity are within the specifications of the device and avoid exposing it to harsh environmental conditions.
Precautions for Use of The SPT Sampler
Calibration and maintenance: Before using the SPT Sampler, the instrument should be calibrated to ensure its accuracy and stability. At the same time, regular maintenance and repair, including cleaning and replacement of filter elements, to ensure the normal operation of the instrument.
Sampling location selection: A representative area should be selected for sampling, avoiding places where there are sources of interference or contamination. At the same time, avoid sampling locations too close to walls, equipment, or other objects that may affect the sampling results.
Sampling time and frequency: Determine the appropriate sampling time and frequency according to the purpose and requirements of the monitoring. Longer sampling periods can yield more comprehensive data, but can also increase the complexity and cost of analysis.
Sampling flow and rate: Set the appropriate sampling flow and rate according to needs and instrument specifications. These two parameters directly affect the volume of air sampled and the efficiency of the sampling. Flow rates that are too high or too low may result in biased sampling results.
Sample preservation and transportation: Collected samples need to be properly preserved and transported to maintain sample integrity and stability. Samples should be kept in sealed containers and avoid exposure to heat, direct sunlight, or chemicals that may affect the quality of the sample.
Data analysis and interpretation: At the end of the sampling period, the collected samples shall be analyzed and interpreted. According to the purpose and method of monitoring, reasonable data processing and statistical analysis should be carried out in order to draw accurate conclusions and inferences.
Safety precautions: Pay attention to safety during operation. Wear appropriate protective equipment and avoid contact with potentially harmful substances. At the same time, follow the relevant operating procedures and safety guidelines to ensure a safe and reliable operation.
